T all whom it may concern:

Be it known that l, (hr-mans Pl. CLARK, a resident of Grafton. in thecounty of Allegheny and State of Pennsylvania, have invented certain ne\and useful Improvements in ()re Dump-Cars, (it which the following is aspecification.

. This is a division of my application 50- rial No. 456,.J77, tiledOctober 5, 1908, and has particular reference to doors of novel form forthe bottom opening. The doors close beneath said opening. and one objectis to'provide the doors with wallming portions for the door-inclosedspace.

A further purpose is to so form the doors as to prevent material fromoverflowing the door ends when discharging from the hopper.

Still a turtner purpose is to provide doors which may move to and fromfull open position without interfering with other parts of the caradjacent the doors.

In the accon'ipanying drawings, Figure 1 is a-vcrtical section of a dumpcar, taken online ll of Fig. 2, and Fig. 2 is a vertical cross-sectionon line of Fig. 1, the doors being shown open in dotted lines.

Referring to the drawings, 2 are the side sills, 9 the side sheets orgirders, and -11 the sloping end floor sheets which meet the lowervertical portions 10 of sheets 9 to form the hopper month which boundsthe bottom opening.

In the present adaptation the bottom opening is closed by doors locatedtherebeneath, the space between said opening and the ('loorsdmreasing indepth from each side inwardly to the center where the doors closetogether. Two oppositelyinclined bodily movable door-s15 are shown, eachsupported at its ends by wheels 21 and' 23 secured to the door ends 16,Wheels 21 moving on inclined tracks 24 at the center of the car, andWheels 23. on inclined tracks 26 at opposite sides of the car. The doorsmay be actuated by any suitable mechanism. In the present adaptation theupwardly extending end portions 16 of the doors are of substantiallytriangular shape, their top edges on being horizontal when closed to fitthe lower extremities of end sheets 11, and their inner edges 6verticaland 'closing together, as shown. The upwardly extending portions16 thus form end walls'for the door-inclosed space beneath the hopperopening, and when 'said opening when the doors are I closed.

Also, the flared ends direct-the discharging material onto thelongitudinally contracted portions of doors when open. Doors of the formshown, longest at the most elevated portions adjacent the car sides anddecreas ingin width toward their inner lower edges.

may move to and from, full open position without interfering with otherparts ol the car having fixedposition relatively to the doors.
